TKN WIreless NetworkS Testbed

The TKN WIreless NetworkS Testbed (TWIST), developed by the Telecommunication Networks Group (TKN) at the Technische Universität Berlin, is a scalable and flexible testbed architecture for experimenting with wireless networks and applications in an indoor setting.

It provides basic services like node configuration, network-wide programming, out-of-band extraction of debug data and gathering of application data, as well as several specific features:

  • experiments with heterogeneous node platforms
  • support for flat and hierarchical setups
  • active power supply control of the nodes

The self-configuration capability, the use of hardware with standardized interfaces and open-source software makes the TWIST architecture scalable, affordable, and easily replicable.

More information about the TWIST architecture and features can be found on the Testbed Components.

Access Interface

To schedule and control jobs on the local TWIST.Sensor instance, please use the TWIST Web Interface. To access TWIST.Wireless instance please refer to Wireless Getting started


Due to construction works in the building some nodes might have changed locations or not be operational.


Terms of Use

Granting access to TWIST is conditioned on an informal “contract” between the external users and TKN that contains information about:

  • the nature of the intended experiments (due to the privacy implications);
  • commitment to a reciprocal access to eventual testbed resources; and
  • agreement on proper acknowledgement of TWIST in the produced publications.

After we receive the above information (e-mail to is enough), and pending an approval by prof. Adam Wolisz, we will enable the account.

Due to high levels of contention for accessing the testbed, in the name of fair access, we are forced to limit the maximum duration and number of job slots available per user. The current quotas are:

  • max job slot duration: 48h
  • max number of jobs per week: 1


We maintain priority access policy for TKN users, so we can not guarantee the availability of the testbed for extended periods of time.
